The plot of "Courir" is being kept under wrap. Its title is inspired by a famous Jean de la Fontaine fable.

Etienne Comar, who collaborated with Xavier Beauvois on the script of Cannes' grand prize winner "Of Gods and Men," co-wrote "Courir" with Maiwenn.

Lensing is skedded for March 3.

Since making her directorial debut with "Pardonnez-moi" ("Forgive Me"), Maiwenn has established herself as one of Gaul's leading femme helmers.

"Polisse," a gritty drama set at a Paris' child protection unit, competed at Cannes, where it won a Jury award and earned warm reviews. Sold by Wild Bunch, the pic was acquired by IFC for U.S. distribution. Pic had a solid run in France and grossed over $20.3 million worldwide.

Leading a career in France and in the U.S., Cassel - who's repped by CAA and Adequat -- stars in very few Gallic movies. He will next be seen in Christophe Gans' "The Beauty And The Beast" with Lea Seydoux.
